Viewing Zoho Support Request Attachments in Zoho CRM - Not Working

We regularly view our client's support requests in the CRM, as they are attached to the client's profile there. However, if the client provided an attachment in their email, when trying to view it we receive an error message once the PDF file is downloaded that it cannot be opened. The same attachments open fine from within Zoho Support, so it appears to be an issue within the Zoho CRM integration.
